rudder horn wear from tailwheel

The holes in the control horn where the control chains from the tailwheel tie in are starting to slowly elongate due to action of the steel end-rings against the aluminum horn. Is there an easy fix for this?
 
Rocket Steering link or Silver Bullet? Those bolt on with bearings. No fastener movement at the horn.
 
Otherwise, maybe you could press in a dedicated insert that would be a known-to-wear item that you could replace from time to time (probably not that often).
 
Thought about that myself

Not flying yet, but that alum horn looks like a wear area. I've thought about riveting a 4130 steel doubler onto the alum.

Just addressed this last month...

Here is a thread with a couple pictures:

Might be the thread Dan remembers! I like to keep my tailwheel chains very tight, and that might controbute to the wear. I have now flown a couple of planes with the tailwheel link, and liked them - I might retrofit if I find a need to replace the chains or springs.

Bush it

My first thoughts....e.d permitting of course.... is to ream the elongated hole up to a specified diameter (driven by the o.d of the repair bushing used) and press fit a .1890 i.d. steel bushing. A pneumatic squeezer or even a C-clamp can be pressed into service to set the bushing. Tip: Remove the bushing from the deep freezer just prior to installing it. This is a situation in which the technique of "pulling holes" to maintain e.d. can prove to be handy.

I installed the eybolts in the rudder horn. They work great. I don't know what Van's is thinking sometimes. The basic design is great but some of the details are completely inadequate and/or unairworthy.
